- Mechanical Directional Control Valves
- Pilot Operated Check Valves
- Pilot to Open Vented
- Pressure at (2) overcomes the spring-bias poppet and allows free flow to (1)
- Flow in the opposite direction, from (1) to (2), is blocked by the poppet
- When the required pilot pressure is acheived at (4), the poppet unseats and allows flow between (1) and (2)
- Port (3) is vented to tank to keep one side of the pilot piston low pressure and isolated from back pressure at port (2)
- The pilot piston area to poppet seat area ratio is 3:1
- Vented pilot design
- Hardened parts for long life
- Industry common cavity
